I spent a month on this board, working hard every day to keep my name on the leader board. Then a couple of months later, they had a crash, and lost all the historical data. So I had to do it again.
I enjoy solving cryptograms, but cracking the hundreds necessary, every day, to get a a ranking starts to feel like work.
So now, and until they lose their data again, I just come by every now and again, and dabble.
